Issues with Office Products

[Andy83]

So I had no issue with Word earlier today but tonight when I went to open it, I got greeted by two Avast messages that said "Avast has blocked access to https://uci.edog.cdn.office.net/ because one of the issuers of the server certificate has expired" and the other one had "support.content.office.net" listed as the website. Once I close out of the messages, I can still access my files but when I close out of Word and reopen, I get the two messages again. I tried opening Excel and same thing. Other members of my family with Avast have the same thing happen to them on their computers. My Avast client is all up to date.

I can't seem to find anyone else talking about this but seeming that it just popped up tonight, it could just be that fresh of a topic that the word hasn't gotten out there. I am guessing this is just something we have to wait out?

I just encountered the same problem this morning for excel and Word. Can't find any help anywhere to fix the problem.

I have the same problem, looks like one of Office's CDN SSL certificate expired a few hours ago and hasn't been renewed yet.
For now I've fixed it by adding an exclusion for that office cdn to avoid getting this alert everytime some app from the Office Suite is opened.

I have the same problems.

@Alessio15 can you post what exclusion you did and has it worked? I've tried  adding url exclusion for uri.cdn.office.net but it doesnt seem to be working.

@Alessio15 can you post what exclusion you did and has it worked? I've tried  adding url exclusion for uri.cdn.office.net but it doesnt seem to be working.

I added the two CDNs in the exclusion list inside each active policy (Exclusions > All scans and shields > URL Addresses).
Originally I just added "cdn.office.net" hoping it will catch all the subdomains, but after 1 user reported that was still seeing the alert, I also added the two URLs, just to be sure:
https://uci.edog.cdn.office.net
https://uci.cdn.office.net

So far no one told me that the alert appeared again, so looks like it has been resolved, but I wasn't able to replicate the issue on my machine, even before the exclusions, so I have no way to confirm this is the right way to proceed. So far no one else has complained about seeing the alert again, so seems resolved to me.

Hope this helps!

Thanks. I didn't put the https:// in didn't think it would be neccessary. It's only been reported by 2 users to us. Depends on which MS server their accessing.

I received the alert this morning as well when booting up my system.
I've reported the problem to Avast. Let's see if that helps.

The certificate provided by these URLs seems indeed expired, so Avast's alert itself is correct. It is up to Microsoft to fix.
